Poorly designed products leading to issue for animals. Avoid at all cost getting their drop in tank heaters. Does not stay flat to the bottom of the tank and ends up on its side or floats vertical if moved because the cord comes from the side instead of the top. That design flaw right there is dangerous to your animals because it touches their nose or the horses figure it's a toy and they pull it out of the tank.

I bought this prior to winter of 2024, it worked fantastic in plastic stock tank With -7 temperatures no freezing H20!

Works very well they last a very very very long time.

blew fuse then unit died. had to get a different one
